JOHN W. GRAHAM, OF HIN'TON, WEST VIRGINIA.

TYPOGRAPHICAL OR SLUG-CASTING MACHINE.

Specification of Letters Patent.

Patented May 15, 191 *7.

Application filed July 19, 1915. Serial No. 40,804.

To all whom it may concern Be it known that I, JOHN W. GRAHAM, a citizenof the United States, residing at Hinton, in the county of Summers andState of West Virginia, have invented certain new and usefulImprovements in Typographical or Slug-Casting Machines, of which thefollowing is a specification.

My invention relates to typographical machines such as linotypes oftheoriginal construction, wherein circulating matrices are released froma magazine in the order in which their characters are to appear inprint, and then assembled in line, together with expanding spacers, thecomposed line brought in contact with the face of a mold, the moldfilled with molten metal to form a line of type or slug against the faceof the matrices, which produce the type characters thereon, and thematrices thereafter returned to the magazine from which they wereoriginally drawn.

More particularly it relates to that class of machines-having a seriesof magazines, in connection with means whereby any maga-.

Zine of the seriesmay be brought into operative position, and whereinthe magazines are removable and interchangeable.

My invention is embodied in the new and novel construction of the framewhich supports and guides the magazines up and down on their line oftravel, and in the automatic locking device, and particularly in thefeature of the locking device, whereby the mag azine in operativeposition when locked is moved forward, and wherein the guide roll ers Dare engaged in slots provided in the arms A and B, and the furtherfeature that when the lock operating roller L is. moved to any magazinewhich is desired to be next brought into operative position, that themagazine already in operative position is automatically unlocked andthrown back, so that the guide rollers are disengaged from the slots,and the magazines are free to be moved up or down as desired, andwhereby when the dial is set to change from the magazine in operativeposition, to any other .magazine, and the. series of magazines is.

then raised and lowered as desired, the magazine which is set to come inoperative position moves forward and is locked in posi- I tionautomatically. My invention also covers the feature whereby the entrancechan nel slides outward automatically when the magazine is unlocked. Theentrance channel is also hinged to the block on which it slides, and maybe turned back by hand at any time without interfering with the look,but this last feature is no part of this invention.

In the accompanying drawings I have shown my invention as applied to alinotype machine, but obviously it may be applied to other machines, andmany changes and variations could be made therein without departing fromthe spirit or principle of this invention, and I wish it understood thatI do not limit myself'to any form or embodiment except in so far as suchform or embodiment is specified in the claims.

Referring to the drawings, Figure l is a side view of a portion of alinotype machine having my invention applied thereto. Fig. 2 shows aside View of a portion of Fig. 1 with the lock operating har E, removed.Figs. 3 and 3 are views at right angles showing the lock operating bar.Fig. 4 shows a top view of a magazine resting in its rack, and also thelocking mechanism. Fig. 5 is a side view of the racks showing how eachrack supports the rack above by its rollers D Fig. 6 and Fig. 6 show thechannel entrance in and out of operative position. Fig. 7 shows part ofthe mecha nism for raising and lowering the magazines. Fig. 8 shows thescrews to raise and lower the lock operating rollers, and the shaftconnecting the two screws.

Referring to Fig. l,

In operating the machine Fig. 1 shows the central magazine locked inposition.

The magazines are numbered, preferably from the top; in this instance 1,2, 3, 4, and 5, and the wheel K is so geared to the screw L that, of arevolution of the shaft K will turn the screws L sufficiently to movethe block with its attached roller L a distance equal to the distancefrom the center of one rack to the center of the next rack. The dial Kis rigidly aflixed to the bearing K which supports the frontal end ofthe shaft K. The hand wheel K on the shaft K has attached to it apointer or finger; the said dial is graduated to suit the number ofmagazines in this instance five; therefore the dial is numberedpreferably 1, 2, 3, 1, 5. In Fig. 1 the central magazine No. 3 is inoperative position; to illustrate, we will assume that it is desirableto bring the lower magazine No. 5 to operative position. To do this thehand wheel K is turned until the finger points to the Fig. 5 on thedial. The shaft K is connected to the screw L on the side of themagazines by bevel gears and these gears are so proportioned that thesaid turn of the hand wheel K operates the said screw sufiiciently tobring the roller L down to the center of the lower magazine No. 5. Theroller L is affixed to the block L which block is in the form of athreaded nut, the thread of which engages the screw L. hen the block Lwith its connected roller L is lowered as above stated it allows thespring.

E to throw the bar E back and disengages the guide rollers D from thenotches in the arms. The crank N on the shaft N is now turned and themagazines raised. When the lower magazine No. 5 is about to come intooperative position the roller L which is standing central of thismagazine and which moves upward with the series of magazines, engagesthe stationary rollers E on the bar E, Fig. 1, forcing the bar forwardand locking the desired magazine No. 5 into the notches provided in theguide arms. The roller L can be brought to rest at any desired magazineand the said magazine automatically locked in operative position asabove illustrated. The entrance channel G is moved automatically in andout of operative position by means of the connecting rod E The arms Aand B are made slotted so as to receive the guide rollers D and guidethe racks in their travel. The arms are bent back at a point above theoperative position so as to guide the uppermost magazines back out ofthe way of the operator.

Having described my invention, its construction and operation, what Iclaim and desire to secure by Letters Patent of the United States, is asfollows:

1. In a typographical machine the combination of a plurality ofremovable magazines, racks therefor, guide rollers on said racks, armsto engage the guide rollers, there being notches in the said arms toreceive the guide rollers of the magazine to be locked in operativeposition.
